Answer to Question #333760 in General Chemistry for fades

Question

A toy dart gun uses a spring with a spring constant of 35 N/m. To use the dart gun, you compress the spring by pushing in a dart of mass 0.002 kg.

a. If you compress the spring by 0.02 m, what force is the spring exerting on the dart? (2 points)

b. With the spring compressed 0.02 m, how much elastic potential energy is stored in the spring? (3 points)

c. If you release the spring, it pushes the dart forward. What is the kinetic energy of the dart when it reaches the natural length of the spring? Explain how you found the answer. (2 points)
